WATER-INLET VALVE FOR FLUSH-TANKS.

OF PITTSBURG, PENNSYLVA NIA.

Specification of Letters Patent.

Patented May 11, 1909.

Application filed March 10, 1908. Serial No. 420,171.

To all whom it may concern:

Be it known that we, EMLYN MoRRIs and CLARENCE RINAMAN, citizens of theUnited States, both residing at Pittsburg, in the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Water Inlet Valves for Flush-Tanks; and we do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

his invention relates to an improved inlet-valve for flush-tanks; and itconsists in the certain details of construction; and combination ofparts, as will be fully described hereinafter.

In the accompanying drawings :Figure 1 is a central side sectionalelevation of our improved inlet-valve for flush-tanks, the same beingconstructed and arranged in accordance with our invention. Fig. 2 is anend elevation of the same, a portion of the to being broken away. Fig. 3is a detailed side elevation of the movable centrally-arranged tube andtop extension of the same.

To put our invention into practice, and thereby provide a valve forregulating and controlling the flow of water into flush-tanks forwater-closet purposes, we provide a cylindrical shell in two parts, anupper and lower, the one joined to the other. The lower section 2, ofthis shell comprises a downwardly-extending threaded member 4, having acentral bore 6, a flange 3 and upwardly-extending externally threadedboss by which means it is attached to the upper section 2 of the shell.The lower section 2 of the shell is attached to the tank 1, by means ofa large nut 5, in the usual manner. The upper section of the shellcomprises a body-portion 2, cylindrical in form, the lower end of whichis formed with an internal thread to engage with that of the lowersection 2 and bring the two parts in perfect axial alinement. This uppersection 2 is also formed with an enlarged portion 13, with openings 15at either side, and also with oppositely-arranged slots 8 near the upperend, through which an operating bar 25 passes. Arranged within the boreof the upper section 2 is a stufling-box 17, having a 1 serrated flange16, and threaded to engage a portion of the interior thread of saidsectionby means of which packing 18 may be con, fined about a centrallylocated tube 9. This tube 9 is formed with an enlargedupwardly-eXtending portion 7, an intermediate circumferential groove 11,a recess 8 near the top and several small perforations 10, saidperforations being located near the top of the reduced part of saidtube. The circumferential groove 11 is for the purpose of holding awasher 12, which operates within a cylindrical bore of the gland 17 ofthe stufling-box.

Attached to or formed integral with the upper section 2 of the shell areoppositelyarranged brackets 14 and 15, the one bracket 14 supporting abell-crank and the other 15, the one end of a pivoted bar25. This bar 25is pivoted at one end by means of a bolt 27,

and lower enlarged portions 26, which portions are located within therecess 8 of the plug 7, and the other end of said bar is pivoted by abolt 24 to a short coupling link 22, which in its turn is connected by abolt 23 to one end of a bell-crank. This bell-crank consists of ahorizontal part 21 and a vertically-arranged arm 20, the upper extremityof which is formed with a threaded boss to support the rod 28, of anordinary float 29.

In operation the water-supply pipe is connected to the threaded portion4 at the base of the shell by the use of ordinary fittings. The waterbeing in the tank 1 the float 29, and the parts of the valve will be inthe position shown at Fig. 1 of the drawings. l/Vhen the tank is flushedthe float descends thereby elevating the horizontal part 21 of thebellcrank, which movement is transmitted to bar 25, giving its free endan upward movement, thereby elevating the tube 9, to bring theperforations 10 of the same above the level of the gland and permit thewater to flow to refill the tank, and when the water has reached itsnormal level the perforations 10, will have moved to a position toshut-ofl the flow of water.

Various slight modifications and changes may be made in the details ofconstruction without departing from the spirit of the in vention.Therefore we do not wish to confine ourselves to the exact construction,shown and described, but wish to claim all such as would come properlywithin the general scope of the invention.

to the bracket 15, and is formed with upper Having thus described ourinvention, What We claim, and desire to secure by Letters Patent, is:

An automatic inlet-valve for flush tanks, comprising a shell formed intwo sections, the one joined to the other in a vertical line and havinga longitudinal bore reduced to form a seat for suitable packing, acentrally located vertically-moving perforated tube having an enlargedupper portion and an intermediate groove, a gland arranged to saldpacking about said tube, a

compress second packing attached to said tube and adapted to fit Withinsaid gland, openings in the upper section of the shell to permit theescape of the Water, a recess formed in the upper portion of said tube,a bar operating in said recess means for pivoting one end of said barenlargements formed on the bar to fill the recess, a bell-crankconnected to said bar, means for pivoting said bell-crank and means forattaching a float to the upperend thereof, as described.

In testimony whereof, We afiix our signatures, in presence of twoWitnesses.
